POCKET-KNIFE.`

SPECIFICATION forming part of Letters Patent No. 702,968, dated June 24,1902.

I Application led April I7l 1902. Serial No. 101,815. (No model.)

My invention relates to improvements inY knives, and more particularlyin pen or pocket knives; and the object of the invention is to devise avery cheap and simple form of knife which will be strong and light andyet durable and capable of a greater range of usefulness than anordinary pocket-knife; and it consists, essentially, of aknife formed ofa handle struck up in one piece and the blade suitably secured in oneend of the handle and the opposite end of the handle being arranged toform a spring the force of which is exerted on a shoulder formed on thehandle behind the pivoted end of the blade, the parts being arranged andconstructed in detail as hereinafter more particularly explained.

Figure l is a plan view of the blank forming the handle. Fig. 2 is aperspective view of such blank as formed up preparatory to receiving theblade. Fig.' 3 is a perspective view showing a complete knife. Fig. 4 isa perspective view of an alternative form of knife. Fig. 5 is across-section through the line a b, Fig. 4. Fig. 6 is a cross-sectionthrough the line oc y, Fig. 4. Fig. 7 is a detail of another alternativeform. Fig. S is an end view through the line 0o' y', Fig. 7.

In the drawings like letters of reference indicate corresponding partsin each figure.

A is the blank forming the handle, which comprises two portions A andA2, the portion A having a slot d near the end and a projection a, andthe portion A2 having a hole d2. The two portions A and A2 are connectedby a bridge a3, which is provided with a series of slots CL4, which aredesigned when the knife is riveted in the position shown in Fig. 3 togive increased resiliency to the handle.

B is the blade, which is secured in the free ends of the portions A andA2 by means of the rivet'O, which extends through the blade and theportions A' and A2 and is provided with suitable flat heads C. It willbe noticed that the rivet has a reduced end c at one side.

It will be seen on reference to Fig. 2 that the portion A2 is offset orhas the free end lower than the free end of the portion A', andconsequently when the blade is fitted in p0- sition the shoulder d',abutting the blade, will by virtue of the continuous spring-pressureimparted to the handle by the offset when opened hold the blade securelyin line with the handle or when closed hold it securely closedsubstantially in line with the handle.

In'Fig. 3 I show an eraser D, inserted in the open end of the handle A,such eraser being held by the spring between the two portions A and A2.

In Figs. 4 and 5 it will be seen that I show the bridge A5 on theopposite side to that shown in Fig. 2. In this construction also I showthe side of the knife with inwardly-bent lips A, whereby a pencil orother suitable instrument may be held in place from end to vend of theknife.

In Figr' I show the bridge of the handle with diagonally-placed slotsd2, which are designed to give both sides of the handle a spring and yetallow of the sides of the handle being made of the full width, butcloser together. The shoulder a' of course is similarly formed on one ofthe sides, so as to hold the blade in position and yet permit ofsufficient resiliency at the ends of the handle, so as toopen and closethe blade. If the knife should be a two-blade knife, of course thebridge A5, which forms the spring, would be placed in the center of thehandle, the blades being one on each end. I have also found that wherethe slots are at an angle, as indicated in Fig. 7, a greater resiliencyis imparted to the spring sides than when the slots are cut at rightangles to the edge of the sides.

I preferably make the end slots connected with the slot formed in theback of the handle in order that I can obtain the benefit of theresiliency of the length of the bars formed between the slots. In Fig. 7of course the diagonally-shaped slots instead of having the bridgeacross the side of the knife I may with equal facility make such bridgeextend across the end of the knife.

It will be seen from the construction of my handle that not only isthere an edgewise spring for the purpose of holding the blade IOC) ` ofa separate piece of metal suitably shaped and suitably fastened to theside of the handle in which the slot is located.

Although I show my invention as particu larly applicable to a knife, itwill be of course understood that a handle so formed orequiv alentlyconstructed might be with equal facility adapted to receive at the freeend any other instrument of utility.

What I claim as my invention isl. In a pocket or other knife, thecombination with the blade, of a spring-metal handle comprising twosides, the end of one side of which is provided with a round hole andthe end of the other with a slotted hole and a projection designed toextend underneath the inner end of the blade, the opposite end of thehandle being provided with a bridge, whereby a spring is imparted to theblade, and a rivet extending through the end hole and slot and hole inthe blade as and for the purpose specified.

2. In a pocket or other knife, the combination with the blade, of aspring-metal handle comprising two sides, the end of one side of whichis provided with a round hole and the end of the other with a slottedhole and a projection designed to extend underneath the inner end of theblade, and the opposite end of the handle being provided with a bridgehaving cross-slots, whereby a spring is imparted to the blade, and arivet extending through the end hole and slot and hole in the blade asand for the purpose specified.

3. In a pocket or other knife, the combination with the blade, of aspring-metal handle comprising two sides, the end of one side of whichis provided with a round hole and the end of the other with a slottedhole and a projection designed to extend underneath the inner end of theblade, and the opposite end of the handle being provided with a bridgehaving diagonal side cross-slots whereby a spring is imparted to theblade, and a rivet extending through the end hole and slot and hole inthe blade as and for the purpose specified.

et. In a pocket or other knife, the combination with the blade, of aspring-metal handle comprising two sides, the end of one side of whichis provided with a round hole and the end of the other with aslotted'hole anda projection designed to extend underneath the inner endof the blade, and the opposite end of the handle being provided with abridge whereby a spring is imparted to the blade, and a rivet extendingthrough the end hole and slot and hole in the blade, the end of thehandle being open and designed to receive an instrument of utility asand for the purpose specified. l

5. In a pocket or other knife, the combina'- tion with the blade, of aspring-metal handle comprising two sides, the end of one side of whichis provided with a round hole and the end of the other with a slottedhole and a projection designed to extend underneath the inner end of theblade, the opposite end of the handle being provided with a bridgewhereby a spring is imparted to the back of the blade, and a rivetextending through the end hole and slot, and hole in the blade, and theopposite side of the handle from the bridge being provided with lipsdesigned to receive an instrument of utility as and for the purposespecified.

6. In a knife, ahandle comprising two sides formedintegrally of springmetal with abridge connecting them at one end, one side being providedwith a hole and being offset in relation to the other, which is providedwith a slot and projection between which hole and slot the blade is heldby a rivet as and for the purpose specified.

7. In a knife, a handle comprising two sides formed integrally ofspringmetal with abridge connecting them at one end, one side being providedwith a hole and being odset in relation to the other, which is providedwith a slot and projection between which hole and slot the blade is heldby a rivet, such bridge forming an edgewise-pressing spring at the freeend of the sides and an inwardly-pressing spring at the bridge end asand for the purpose specified.

8. In a knife orsimilar article havingabuttend for fastening suchinstrument in place, a handle comprising two sides formedintegrally ofspring metal with a bridge connecting them at one end, one side beingprovided with a hole and being Offset in relation to the other, which isprovided with a slot and a rivet 0r pin extending through the hole inthc slot and the butt-end of the knife as and for the purpose specified.
